The key to automatic transmission life is keeping the fluid fresh, clean and cool. When fluid temperatures exceed the optimum operating range of 160°F to 200°F it begins to break down, decreasing the life of the fluid and in turn the life of the seals, bearings and all moving parts.
 
The #1 cause of automatic transmission failures is overheated transmission fluid. Today’s cars generate extremely high under-the-hood temperatures. Add to that the heat generated by an automatic transmission, and you’ll see why adding an auxiliary transmission oil cooler is a must for guarding against costly transmission repair.
 
Installation of a Battle Bee CVT Cooler kit will reduce your transmission oil temperature as much as 40 degrees, which will help prevent transmission burnout and extend the life of the transmission.
